Syzygium cumini has been used in folk medicine to treat many diseases. To establish the potential medicinal value of leaves of S. cumini, the current study was carried out to assess the peripheral analgesic and anti-diarrheal activities in mice model. The crude methanol extract and its petroleum ether and chloroform soluble fraction were administered to the experimental mice at a dose of 200- and 400- mg/kg b.w. (denoted as CME1, CME2, PESF1, PESF2, CLSF1 and CLSF2 respectively) using acetic acid induced writhing method and castrol oil induced anti-diarrheal assay protocol. The extract and its Kupchan fractions exhibited significant (p < 0.001) reduction of writhing response in a dose dependent manner. In the acetic acid-induced writhing test, the activity decreased in the order diclofenac (75.33%) > PESF2 (70.33%) > CME2 (67.00%) > PESF1 (64.00%) > CLSF2 (61.33%) > CME1 (56.67%) >CLSF1 (48.67%). All the fractions significantly (p < 0.001) attenuated anti-diarrheal effect in a dose dependent manner with the highest activity observed by CME2 (47.73%) as compared to standard lopeiramide (54.55%). The results of our study, being reported for the first time, provide reasonable indication that the methanol extract of S. cumini leaf and its different fractions possess peripheral analgesic and antidiarrheal activities.

Aganosma dichotoma (Roth) K. Schum. is an indigenous plant of Bangladesh. Traditional healers use this plant to treat many diseases. In order to systematically explore the medicinal values of this plant, the crude methanol extract of leaves of A. dichotoma were screened for analgesic and antidiarrheal activities in mice model. The peripheral and central analgesic actions were determined by using acetic acid-induced writhing and tail immersion methods. The extract significantly (p < 0.05) attenuated the acetic acid-induced writhing in a dose dependent manner. A noticeable dose-dependent increase (p < 0.05) of latency period was also observed in the tail immersion method. In the castor oil induced anti-diarrheal assay, the extract exhibited significant (p < 0.05) anti-diarrheal effect at a dose of 400 mg/kg body weight.Bangladesh Pharmaceutical Journal 18(1): 15-19, 2015

Hemigraphis hirta has been used by folk practitioners to alleviate symptoms of several diseases, although the pharmacological activities of this plant have not been thoroughly explored. The current study was designed to assess the anti-diarrheal and CNS depressant activities of H. hirta in mice model. For both assays, the experimental mice received the methanolic crude extract and its petroleum ether soluble fraction at dose of 200 and 400 mg/kg body weight which are denoted as CME 200, CME 400, PESF 200 and PESF 400, respectively. Both fractions remarkably attenuated castor oil-induced diarrheal effect in a dose-dependent manner and the results were comparable to standard loperamide (89.47%). Among all, PESF 400 exhibited statistically significant (p < 0.01) anti-diarrheal activity as demonstrated by 78.95% inhibition of defacetion. Compared to reference drug diazepam, all the tested samples considerably shortened the time for onset of sleep and prolonged the duration of phenobarbitoneinduced sleep in mice. The results of our present study, being reported for the first time, demonstrate that the methanol extract of leaves of H. hirta and its organic soluble partionates possesses significant anti-diarrheal and CNS depressant properties. However, this preliminary screening requires further detailed investigation to confirm these findings as well as to isolate and characterize the bioactive compounds.

Pupalia lappacea Juss (Family: Amaranthaceae) is claimed to be useful in treatment of bone fracture, wounds, boils, cough, toothache, fever and malaria. The study was aimed to evaluate the 80% aqueous ethanolic extract of aerial parts of P. lappacea for antinociceptive and antipyretic activities to verify the traditional claim. The extract was orally administered at doses of 200, 400 and 600 mg/kg. The extract has significantly (P<0.01) reduced the nociception induced by acetic acid. The effect produced was in dose dependent manner. The antinociceptive effect was not reversed by pretreatment with naloxone in acetic acid induced writhing test. In hot plate method, the extract has significantly increased the latency time of jump. The naloxone has partially antagonised the antinociception of extract in hot plate test indicating P. lappacea has morphinomimetic properties. In the study of the CNS-depressant effects, the extract was found to produce significant reduction in head pokes and locomotion in mice by using hole board and locomotor activity test respectively. The extract has significantly reduced the rectal temperature in yeast induced pyrexia in rats at 600 mg/kg. The activity produced by extract was in dose dependent manner. Phytochemical investigation of ethanolic extract of P. lappacea revealed the presence of steroids and/or triterpenoids, flavonoids and phenolic compounds which may be responsible for antinociceptive and antipyretic activity of P. lappacea.DOI: http://dx.doi.org/10.3329/icpj.v2i2.13193 International Current Pharmaceutical Journal 2013, 2(2): 23-28

Argenome mexicana Linn. (Family: Papaveraceae) is traditionally used to relieve inflammatory and pain-related health conditions. It is also used as laxative. The intraperitoneal median lethal dose (LD50 ) of the methanol extract was determined in mice. The methanol extract of the plant was 50 evaluated for antinociceptive effect using acetic acid-induced writhing test in mice and formalin induced pain test in rats. Fresh egg albumin-induced oedema model was used to test for its antiinflammatory effect in rats while the gastrointestinal effect was tested using gastrointestinal motility (transit) model in mice. The intraperitoneal LD value in mice was calculated to be 894.4 50 mg/kg. The extract (75, 150 and 300 mg/kg i.p) significantly (p< 0.05) and dose-dependently inhibited acetic acid-induced pain with the values of 44.83%, 68.97% and 81.38% respectively. Acetyl salicylic acid (ASA; 150 mg/kg i.p) also significantly (p<0.05) inhibited pain with inhibitory value of 65.52%. The extract (75, 150 and 300 mg/kg i.p) significantly (p< 0.05) and dose-dependently inhibited the early phase of formalin-induced pain with values of 56.76%, 75.68% and 78.38% respectively. The extract at the same doses also inhibited the late phase of formalin-induced pain in a dose-dependent manner with the values of 39.51%, 55.56% and 74.08% respectively. The late phase inhibition was only significant (p<0.05) at the doses of 150 and 300 mg/kg i.p. The magnitude of pain inhibition by the extract was higher in the early phase. The extract (75, 150 and 300 mg/kg i.p) produced a dose-dependent inflammatory inhibition with percentages of 15.00 %, 25.00 % and 73.34% respectively. ASA (150 mg/kg i.p) produced 36.67% inhibition. The extract produced gastrointestinal movement inhibition of 54.70%, 55.47% and 73.32% respectively. The inhibition was significant (p < 0.005) only at 150 and 300 mg/kg i.p while atropine (0.1 mg/kg i.p) produced a significant (p < 0.05) inhibitory effect with percentage of 63.94%. The study provided scientific justification for the traditional use of A. mexicana in pain and inflammatory health conditions but did not justify its use as a laxative.

Traditional medicines including Ayurveda, Unani have been used as therapeutics in the Indian subcontinent since 5000 BC. Because of the abundance of secondary metabolites, medicinal plants are becoming priceless natural resources for better drug development. Till date almost no ethnopharmacological evidences were available on Colocasia genus except Colocasia esculenta. As a part of our continuing assessment of evidence based use of traditional medicine, we have identified bioactive polyphenols in the ethanolic leaves extract of Colocasia affinis Schott using HPLC-DAD method and evaluated its anti-allergy, anti-inflammatory and anti-diabetic potentials for the first time. Chromatographic investigation showed the presence of p-coumaric acid, trans-ferulic acid, rosmarinic acid, myricetin and kaempferol in the leaves extract. Pharmacological profile exploration demonstrated its anti-inflammatory activity at a dose of 250- and 500-mg/kg in xylene-induced ear edema in mice. The extract significantly reduced the allergy like symptoms such as sneezing, scratching, rhinorrhea, redness and swelling in Tolune diisocyanate (TDI) sensitized allergy model mice at 250- and 500-mg/kg doses. Besides, the extract also exhibited reduction in the level of neutrophils, lymphocytes and eosinophils in a dose dependent manner in the experimental animal. The extract also confirmed reduction of blood glucose levels in the experimental mice at a dose of 250- and 500-mg/kg. Therefore, it is evident that C. affinis demonstrated possesses medicinal values through its anti-inflammatory, anti-allergic and anti-hyperglycaemic potentials.

The article deals with the history of the study and the current state of research of physiological and biochemical properties of the plant genus Sedum that are useful for human and has been used in folk medicine for many years. It was noticed that antioxidant properties of extracts from plants S. sarmentosum, S. sempervivoides, S. takesimense were caused by the presence of phenolic compounds. Methanol extract of plants S. takesimense exhibited strong scavenging activities against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and superoxide radicals as well as significant inhibitory effects on lipid peroxidation and low density lipoprotein (LDL) oxidation induced by a metal ion Cu2+. Various immunomodulatory activities of various fractions of plants extracts (S. dendroideum, S. kamtschaticum, S. sarmentosum, S. telephium) are observed. It was shown that the ethanol extract of S. sarmentosum and it’s fractions suppressed specific antibody and cellular responses to ovalbumin in mice. The methanol extract of plants S. sarmentosum reduced the levels of anti-inflammatory markers, such as volume of exudates, number of polymorphonuclear leukocytes, suppressed nitric oxide synthesis in activated macrophages via suppressed induction of inducible nitric oxide synthase (iNOS). Polysaccharides fractions from plants S. telephium inducing productions of tumor necrosis factor alpha (TNF-α), increasing the intensity of phagocytosis in vitro and in vivo. Methanol extract from the whole part of S. kamtschaticum strongly inhibit PGE2 production from lipopolysaccharide-induced RAW 264.7 cells, a mouse macrophage cell line via modulating activity in gene expression of the enzyme cyclooxygenase-2 (COX-2). The methanol extract of plants S. sarmentosum and the major kaempferol glycosides from S. dendroideum have antinociceptive activity. It was noticed that anti-adipogenic activity of extracts from plants S. kamtschaticum were caused by inhibition of peroxisome-proliferator-activated receptor γ (PPARγ) expression and it’s dependent target genes, such as genes encoding adipocyte protein 2 (аР2), lipoprotein lipase (LPL), adiponectin and CD36. Polysaccharides fractions from S. telephium cause inhibition of cell adhesion of human fibroblast (MRC5) to laminin and fibronectin via interfere with integrin-mediated cell behaviour and they contributed to the role of polysaccharides in cell-matrix interaction. The methanol extract of plants S. sarmentosum exhibited a significant inhibitory activity in the chick embryo chorioallantoic membrane angiogenesis in a dose-dependent manner. The crude alkaloid fraction of S. sarmentosum caused a dose-dependent inhibition of cell proliferation on murine hepatoma cell line BNL CL.2 and human hepatoma cell line HepG2 without necrosis or apoptosis. Alkaloids from plants S. sarmentosum may improve survival of hepatoma patients via the inhibition of excessive growth of tumor cells. Plant’s juices have antiviral activity (S. sarmentosum, S. spurium, S. stahlii). Crude ethanol extract S. praealtum have spermicidal activity of the in mice and a relevant inhibitory effect of aqueous extract on human spermatozoa motility as well as an anti-fertilizing activity in rats. Hepatoprotective triterpenes, e.g., δ-amyrone, 3-epi-δ-amyrin, δ-amyrin and sarmentolin were isolated from S. sarmentosum. 2- and 2,6-substituted piperidine alkaloids (e.g., norsedamine, allosedridine, sedamine, allosedamine) are observed in plants S. acre, which in the presence of data on the use of pyridine and piperidine derivatives for treating neurodegenerative diseases (e.g., Alzheimer's disease), points on the promising research in this area. Taking into account that biologically active compounds are accumulated in the aboveground vegetative organs of plants of Sedum, the prospects of further study of the use of Sedum for the purposes of biotechnology and in the pharmaceutical industry becomes apparent. This work extends the existing views regarding the use of plants Sedum.

AbstractIncreasing evidences in recent years have suggested that regulatory B cells (Bregs) are crucial modulator in various inflammatory disease conditions. However, the role of Bregs in case of postmenopausal osteoporosis remains unknown. Also, no study till date have ever investigated the significance of Bregs in modulating osteoclastogenesis. In the present study, we for the first time examined the anti-osteoclastogenic potential of Bregs under in vitro conditions and we observed that Bregs suppressed RANKL mediated osteoclastogenesis in bone marrow cells in a dose dependent manner. We further elucidated the mechanism behind the suppression of osteoclasts differentiation by Bregs and found that Bregs inhibit osteoclastogenesis via IL-10 production. To further confirm the bone health modulating potential of Bregs we employed post-menopausal osteoporotic mice model. Remarkably, our in vivo data clearly suggest a significant reduction (p < 0.01) in both CD19+IL-10+ and CD19+CD1dhiCD5+IL-10+ B10 Bregs in case of osteoporotic mice model. Moreover, our serum cytokine data further confirms the significant reduction of IL-10 levels in osteoporotic mice. Taken together, the present study for the first time unravels and establish the unexplored role of regulatory B cells in case of osteoporosis and provide new insight into Bregs biology in the context of post-menopausal osteoporosis.

The hexane (HE), dichloromethane (DCME), ethyl acetate (EAE) and methanol (ME) extracts of seed and stem of Anethum sowa were subjected to screenings for analgesic, anti-diarrheal and anti-depressant activities. The peripheral and central analgesic actions were determined by using formalin-induced writhing test and tail immersion method. The DCME extract of stem, at a dose of 200 mg/kg body weight, significantly reduced the number of writhing movements whereas the methanol extract of seed at the same dose exhibited remarkable analgesic activity in tail immersion method. In castor oil induced anti-diarrheal assay, the ethyl acetate extract of stem, at 400 mg/kg body weight, exhibited significant anti-diarrheal effect. In addition, significant anti-depressant activity was observed at a dose of 400 mg/kg body weight as compared to the standard drug in case of HE extract of stem.Bangladesh Pharmaceutical Journal 21(1): 1-6, 2018
